POWER JACKS HAS A HANDLE ON NUCLEAR WASTE

As part of the decommissioning project for Chapelcross Magnox Power Station, BNS Nuclear Services was commissioned to develop and construct a Graphite Handling system and awarded Power Jacks the contract to supply 50kn E series ball screw jacks as part of the application build. Power Jacks long standing history of supplying quality products on time and in budget was one of the many factors why Power Jacks was awarded the contract.

The Graphite Handling system was developed to retrieve graphite components, capping pieces and thermocouples from inside the reactors, crush them for size reduction and deposit them into shielded flasks. The machine itself houses 4 types of flask, each flask has differentials in the

thickness of its shielding. The material is deposited into the selected flask depending on its level of radioactivity. The Graphite Handling Machine makes this selection.

Power Jacks ball screw jacks were the ideal solution to raise and lower the flasks in operation and to operate the crushing jaws in the Crusher, as typical hydraulics were unsuitable for use in the machine.
